But that is exactly the point. cdbs will by default select "cc" as the
compiler, and there is no guarantee anywhere that that is gcc. So in
accordance with what you and I are saying, cdbs should take care that it
really calls gcc.
Or perhaps we should ask for clarification on this matter in a wider audience.
